[EMCAL-1135] Throw exception in case starttime is to large or small

- This commit is an extention for PR: AliceO2Group#13326
- Move error class from base to reconstruction
- added handling of error RawToCell converter: handleFastORStartTimeErrors
- add error type to TRUDecodingError to indicate invalid starttime
